RoboCraft: Learning to See, Simulate, and Shape Elasto-Plastic Object with Graph Networks

Important

  1. Please check out our new paper if interested: RoboCook: Long-Horizon Elasto-Plastic Object Manipulation with Diverse Tools
  2. Please see the dev branch for an improved version of the RoboCraft codebase, especially if you're interested in real-world experiments!

Overview

This is the codebase of RoboCraft in the simulator.

Project Page | Paper

Prerequisites

  • Linux or macOS (Tested on Ubuntu 20.04)
  • Python 3
  • CPU or NVIDIA GPU + CUDA CuDNN
  • Conda

Getting Started

Setup

# clone the repo
git clone https://github.com/hshi74/RoboCraft.git
cd RoboCraft

# create the conda environment
conda env create -f robocraft.yml
conda activate robocraft

# install requirements for the simulator
cd simulator
pip install -e .

Generate Data

  • Run all the blocks in simulator/plb/algorithms/test_tasks.ipynb. Note that it is easier to use ipython notebook when dealing with Taichi env for fast materialization.
  • You can control the number of videos to generate by changing the variable n_vid. The default is 5 for the purpose of debugging. We used 50 in the paper.

Sample Particles

  • cd simulator/plb/algorithms
  • Go to line 598 in sample_data.py and replace the string with the output folder name you just generated in simulator/dataset
  • Run python sample_data.py. Note that this step may take a while.

Build the dataset for GNN

  • You will need to remove the old dataset if you want to update the dataset
cd ../../../robocraft
bash scripts/utils/move_data.sh ngrip_fixed sample_ngrip_fixed_[timestamp of the folder you just generated]

Train Dynamics Model

bash scripts/dynamics/train.sh

Planning with the Learned Model

  • Go to line 6 in robocraft/scripts/control/control.sh and change the model path to the path to the checkpoint you just trained.
  • bash scripts/control/control.sh

Code structure

  • The simulator folder contains the simulation environment we used for data collection and particle sampling.
  • The robocraft folder contains the code for learning the GNN and planning.
